9.3. Independent quality control standards will be prepared under the supervision of a Quality

Assurance Coordinator (QAC) or purchased from an external supplier and analyzed on at least a quarterly basis. Results will be stored in the appropriate file in Gillmor 327 or on separate electronic “server-six$” and reported to the Laboratory Manager and/or electronically by the QAC.

9.4. Quality control performance parameters (e.g., Method Detection Limits (MDLs)) must be

performed at least once a year and are specified in the QA-SOP (hereafter called the Demonstration of Performance). When completed, the SOP and any other documentation specified by the SOP will be updated with the most recent data (hereafter called Validation Data).



SECTION 10.0: DATA REDUCTION, REVIEW, AND REPORTING 10.1. Details regarding data calculation and reduction are listed within the method’s Standard

Operating Procedure (SOP). All calculations are performed electronically by the software of the computer that operates the instrument. Sample information is then transferred from the instrument computer to the laboratory’s main database, the VAX system.

10.2. Data is retained by the laboratory in the form of a paper copy and an electronic version stored on the VAX system. The paper copy of the data is the primary method of data retention and stored in the designated file in Gillmor 327. The electronic data stored in the VAX system is backed-up at least bi-weekly to a disk format and stored in Campus Center 125.

10.3. Quality Control Data is collected for each method according to the Quality Assurance-

Standard Operating Procedure (QA-SOP) and is reviewed by a Quality Assurance Coordinator (QAC) on a 3 or 4 week basis. 10.3.1 Primary responsibility for Quality Control Data resides with the analyst and is

collected on a weekly basis. Data are added to Control Charts and examined to determine if the given system is out of control.

10.3.2 Review of the Quality Control Data by a QAC for the previous weeks’ data must be completed with 2 weeks of the weeks collected. The QAC will report the findings of the review, including any deficiencies, to the Laboratory Manager (See Section 13.0).

10.3.3 Control Charts are stored in the appropriate file in Gillmor 327 or on separate electronic “server-six$” that is maintained by the Heidelberg University Computer Network Information Technologies department.

10.3.4 If any deficiencies are found by the QAC in the Quality Control Data (i.e., a

system that is out of statistical control, etc.), the deficiencies will be brought to the attention of the Laboratory Manager and any applicable analyst. Corrective action measures will be taken until the deficiencies are corrected (see Section 11.0).

10.4. Sample data for each method is reviewed by the QAC on a quarterly basis. Data are

extracted from the River file on the VAX, reviewed for completeness and errors, and corrected as needed. All corrections are documented in a correction log on server.

10.4.1. Primary responsibility for experimental data review resides with the QAC.



10.4.1.1. Using plotting software (e.g., Excel or Datadesk), individual and/or multiple parameters for each location are visually displayed so that disparate data points or “outliers” can be identified.

10.4.1.2. Questionable data are investigated by researching original data

input to discover the possible source of the error or omission. Some accurate data that do not conform to expected patterns may appear to be “outliers”.

10.4.1.3. If the error can be readily explained and documentation is available

with the correct entry, the correction (if necessary) is made in the VAX database and the corrective action is documented.

10.4.1.4. If the error cannot be readily explained and/or documentation is

unavailable, the questionable data are brought to the attention of the Laboratory Manager. A meeting between the laboratory manager and QAC will be conducted to determine the course of action. In most cases, the data will be retained in the VAX, but may be replaced with “-9” in any working databases to indicate missing data, and the corrective action will be documented electronically as “comments” in the data file.

10.4.1.5. Copies of corrected VAX data sets are added to existing working

database servers for use by research scientists and educators. Working databases are updated at least quarterly by the QAC.

10.4.2. It is the responsibility of a QAC to update the appropriate files with the new

experimental data (see Section 9.0).

10.4.3. It is the responsibility of the designee in the appropriate Study Plan to report data generated within the specifications of the QAP to the appropriate agency (e.g., QDC to the Ohio EPA).



SECTION 11.0: CORRECTIVE ACTION PROCEDURES AND CONTINGENCY PLAN 11.1. Corrective action procedures for quality control failures can be found within each

method’s Standard Operating Procedure (SOP). 11.2. If the NCWQR laboratory is unable to perform quality analyses for any reason, samples

will be forwarded to an appropriate contract laboratory for analysis.

12.1.

Table 12.1 NCWQR Accreditations and Certifications

12.2 Internal auditing of the Quality Assurance Plan (QAP) is undertaken during the yearly

review of the QAP, SOPs, and QA-SOP (See Section 14.5) by at least one Quality Assurance Coordinator (QAC) and any other assigned members of the NCWQR.

12.3 A QAC may audit the NCWQR at any time to ensure the proper implementation of the

QAP. If any deficiencies are found, they will be corrected in a timely fashion and noted in the monthly report from the QAC to the Management (see Section 13.0).

12.4 As indicated in Section 9.0, PT samples are purchased from approved vendors (see

Section 15.3) and tested as samples according to the appropriate SOP.

12.4.1 Samples may be diluted given the possible concentrations to ensure they are within the routine working range of the instrument.

12.4.2 After completion of the analysis, results are reported to the PT agency by a QAC.

12.4.3 Acceptable performance is determined by comparing the NCWQR laboratory

result to the Acceptance Range for the analyte.

12.4.3.1 For PT samples from the Water Supply Program (WS), the acceptance range is calculated based upon the United States Environmental Protection Agency Nation Standards for Water Proficiency Testing Program Criteria Document (NERL-Ci-0045). The acceptance limits are defined as ± two standard deviations from the estimated mean. See Table 12.2 for an example.

12.4.3.2 For PT samples from the Water Pollution Program (WP), the acceptance range is calculated based upon the United States Environmental Protection Agency Nation Standards for Water Proficiency Testing Program Criteria Document (NERL-Ci-0045). The acceptance limits are defined as ± three standard deviations from the estimated mean. See Table 12.3 for an example.

Table 12.3

WP PT Sample Acceptance Example

12.4.4 Any PT results determined to be outside the acceptance range will result in an investigation by the QAC. The investigation will involve, but is not limited to the following action items. The findings of the investigation will be noted in the appropriate file in Gillmor 327.

12.4.4.1 The QAC will request a re-test of the remaining PT sample.

Should the PT sample return results within the acceptance range, a note will be placed in the PT file and analysis of the analyte will resume. Should the PT Sample still return results outside of the acceptance range, analysis will halt until a reason for failure can be identified.

12.4.4.2 The QAC will investigate the raw data produced by the instrument.

12.4.5 PT samples can be maintained and used as QC samples as outlined in Section 9.3. The acceptance criteria will be the same as Section 12.4.3.
